IP Camera (Urgent)

Dear All, first i thank you all for your valuable website. i personally got many benefits from your q/a posted.

one very important issue for me is mentioned on your website but it is still not working with me, and i do highly appreciate any one can help.

i want to be able to access my trendnet ip camera from the internet without having a static IP assigned from my ISP Provider.

i have a DSL Connection at home, connected to a router (trendnet) and a wirless trend net camera is connected to the router.

the router ip is 192.168.0.1, the camera IP is 192.168.0.30.

A) on the camera web access app i configured on the camera that the gateway is 192.168.0.1, moreover i configured the DDNS to be: domain name: http://ngkn.dyndns.org user: XX password: YY is that right? any missing config?

B) on the router web app i configure a virtual server: 1. I enabled Virtual server 2. Name: i choose from a drop down list HTTP 3. IP Address: /here is my probelm/ What IP should i Enter? * 0.0.0.0 * or shall i enter the IP Automaticaly Assigned to the router from the DSL Modem on the WAN port * or shoud i enter the IP that i use to access the router 192.168.0.1

1. Protocol: both
2. Private port: 80
3. Public Port: 80 save

is that right? any missing config?

C) The last step is that i went to the website http://DynDNS.org, and i registed an account for free. i could enter a host service:

i entered the followig info: 1. Hostname: http://ngkn.dyndns.org 2. Wildcard Status: Disabled 3. Service Type: Host with IP address 4. IP Address: ALso here i would like to know which IP Shall i enter * shall i use the WAN ip Assigned automaticaly to my router * i dont if it the same ip i got when i enter to the website "what is my IP"

1. What do you want to use this host for? Select services and devices you would like to use with this hostname. i selected DVR, Webcam, and CCTV

so this is my all config. whta should i configure to make it work. the most important issue is that i don't have a static ip assigned to me from the ISP provider. and most of all once evrything configured through which IP shall i access the ip camera? Is it throught the ISP public IP Address? if so, what will differentiate between hundred of people having the same setup connecting through the same ISP provider? they will all use then the same group of public ISP IP's, they will use port 80, hwta will ban the conflit of config setup between my IP Camera and another user IP Camera while both connected to the internet through the same ISP?

Thank you all for your time, and i HIGHLY appreciate if someone can help.
